Versuchsvorschrift
14α-Fluoro-3β-hydroxyandrost-5(6)-en-17-one (400mg) in ethanol (70 ml) was hydrogenated over palladium-charcoal (5%; 250 mg) until uptake of hydrogen ceased (72 hr). The solvent was evaporated in vacuo and the crude product was recrystallised from acetone: hexane to give prisms of
